` Specification forming part of' Letters Patent No. 95,1 l0..` laled September 2l, 18H).V

To allwhom/ t may concern,.-

Be tknown that I, `Comnvrniv Brons, of the town tol" Lancaster, in the county of Garrard, and in the State Of`KentuCky, have invented certain new and useful Improvements in the Construction of `Sash-Locks; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of refereneemarked thereon.

`The object of my invention consists in pro` vidingsash forwindows with locks so' constructedand operated thatl sashes, when `sliding up anddownor back and forth horizontally, in their frames, may, when stopped, be easily and quickly loekedat the point `of stopping" by the use of a simple key, which may `be inserted or withdrawn j at pleasure.

To enable others skilled in the art-to make anduse my invention,3I` will proceed `to describe the constructionand operationof the same. j ,j

In the drawings,Fignre l represents a front view lof facings of a windowwith upper sash and part of lower sash in position. Fig. 2 represents a vertical and side' vie'wof rack and pinion and a section of the facing and frame. Fig.` 3 represents a cross-sectional view of the lower sash and inside view of vthe left facing and frame. Fig. 4. represents ahorizontal sectional viewtakenf through the center of the two locks, sashes, glass facings, and frame. Fig. 5 represents ahorizontal sectional view of the lock, taken through its operative parts. Fig. `6 represents a sideview of the flanged. cylinder D. Fig; 7 represents a front side view ofpinion d. Fig. 8 represents a perspective view ot the clutch-nut E, and Fig. `9 a side view of plate F and edge of plate m. f

"In Fig. 1, A A"`r`e`ltlie`inside easings, cthe upper sash', and c the `lower sash; a (l, the escutcheon, `and b b thedrey-holes. '.lhese parts need no further description.

"Inverder to nintroduce liny lock, a toothed rack, e, Fig. 2, is made,either by casting itin a mold? or by means of a suitable male and female die, bending a suitable strip of sheet metal into the form desired, and that rack is let into the leftside of the left stile of the upper sash alongits entirelength, so that when viewed from the front ofv the sash even the teeth wouldnot be visible, and in a similar manner the right side ,ot the right stile of the lower sash will be provided 4with another rack.

Thewhole of the operative parts of my lock is let into and buried in the fxainro that it is covered and concealed by a metal plate, on, er@I cept a few of the teeth of the pinion. d, as shown in Fig. 3, and when the sash is in place theyare halt` concealed.

The locks for both sashes are placed in the frames at the same height and on a level with the meeting rails of the sashes, as shown in Fig. 1 ,Y

The pinion,flwhen placed upon an axis, as shown 'in Fig. 3, will be revolved by the teeth of the rack when thesash is raised or lowered; and neXt I will give a more' detailed description of the lock itself.' The form of the front side of the pinion (l is shown in Fig. 2, ashort journal, t, being raisedup, as shown, and the form of the rear side, as shown in Fig. 7. A short journal, u, is raised up on that side also', andthe interior of that journal is to correspond with and fit over the teeth of the clutchnut E, both the pinion and the clutch-nut beingperforated with the key-hole b. In Fig. 8 th at clutch-nut appears with its square shaft up ward 5 but in Fig. 'the form and proportions of the square shaft better appear. ,A view of the flanged cylinder D-a front View of `ii'-.-s presented in Fig. 6,a side sectional view inFig. 5, and a horizontal sectional view in Fig. 4. The frontend, a, ofthe cylinder D is hollowed out to iitr over and turn upon the rear' journal of the pinion, the opening `is continued, a little reduced in size, a sufficient depth to accommodate the teeth of the clutch-nut, and it is then made to assume a square form, to correspond with and `lit over the square shaft `of that nut, and to continue in that form so much farther that it will afford space in which to seat the spiral spring la. Then these parts have received their proper forms, the spring is seated, the clutch-nut is inserted with the end of the square shaft against the spring, and the front end of the cylinder is placed over the rear journal of thepinion, and then a metal plate, F, corresponding in form andthicknesys to the flange of the cylinder D,wi th holes corresponding to these inarked 0 o, Figr, and with f e male threads in them.` This plate furnishes a bearing for the front journal of the pinion and becomes a part of the frame of the'lock, as will hereinafter appear. The next important part in that framework is the plate m, a

front View of which is shown in Fig. 3 and a side View in Fig. 2. It is a plain flat plate of nnifoi In thickness, and of sufficient thickness to afford the strength required, with two tongues, ff, projecting from its rear surface, each with a hole passing horizontally through it. These t nigucs are formed with referenceio the fiange ofthe cylinder and the plate 'before described, so that when the plate in is placed over the teeth of the pinion and cylinder, as shown in Fig. 3, the two tongues will pass between said flange of cylinder l) and the said plate F, so that screw-bolts inserted in theholes may pass through the holes t 'n in the tongues and be screwed through the screw-holes in the plate before described, and thus the operative parts of the lock will be bound together, and then, by means of screw-bolts passed through the holes in each end of' the plate m and into the frame, the wholelock is .made fast therein.

It will be noticed that the clutclrnnt is made 'with a hole through its center. This is not essentially necessary.

r Having described the construction of my lock, a few words will be sufficient to explain its operation, if that is not already apparent. The length and stiffness of the spiral spring k or other spring employed are made sufficient to press and hold the end of the clutclrnut, which is provided with teeth entirely within the rear `iournal of the pinion, these teeth having the form of saw-teeth, the crown of each being` a sharp edge, and the rear journalhaving an interior space and indentations exactly corrcsponding. Now, by inserting a key, g, in the keyhole b, it may be passed through to the head of the clutch-nut E, or, if it be perforated, into the hole therein, so that the shoulder ci' the key will press against the end thereof. Then by pressing upon the head' of the key with the hand the spring k is compressed and the teeth of the clutch-nut are forced out of gear, free from the pinion, which may then be made to revolve freely by raising or lowering the sash. I

It will be apparent from the foregoing description that by the usc of my lock a sash may be locked at any point, and as well at one point as at another, and that it locks instantly by relieving the end of the key from pressure.

Vhat I claiin as new, and desire to secure by Letters Patent, is

1. The cluteh-nut E, with its toothed flange and square shaft, constructed substantially as described, in combination with the pinion (l and spring 7c, as a device for locking and unlocking a window-sash, all constructed and arranged substantially as and for the purpose described,

2. The flanged cylinder D, the pinion il, the rack c, spring k, clutch-nut E, all constructed and arranged substantially as described,wh(n in combination, as parts ot' a sash-lock, above set fortln COLEMAN HICKS.
